Connecticut · network infrastructure
PeeringDB records 16 facilities in Connecticut across 9 cities, holding 16 network presences in total. Stamford has the most, six spread over five buildings, and CyrusOne Norwalk carries three in one. Connecticut has no internet exchange in the snapshot, so networks exchange traffic outside the state.

What a Connecticut IP address tells you
Stamford holds six network presences over five buildings, more than any other Connecticut city, with Cloudpath CT19 at two and Cloudpath CT1, Cloudpath CT2, Lumen Stamford and Crown Castle Stamford at one each. CyrusOne Norwalk has three networks in a single building. The recorded sites in Trumbull, Waterbury, Southbury, West Haven, New Haven, Hartford and New London hold one network or none. Sixteen facilities carry sixteen network presences between them, and with no internet exchange and zero peers recorded, traffic leaves Connecticut to be exchanged.
An IP address that geolocates to Connecticut carries the location its operator registered for the block. AT&T, T-Mobile and Verizon concentrate mobile subscribers behind regional gateways, so a device in Hartford can present an address that a database places in another state. The thin spread here, one network in most buildings, means few operators anchor address space to Connecticut, and addresses reaching users in the state are often announced from prefixes registered elsewhere.
The origin ASN and the netname on the specific prefix carry the operator's own record. Verizon's mobile traffic runs through seven ASNs in this snapshot, T-Mobile's through five and AT&T's through five, and one of them can serve a wide area from a small number of gateways. Read those fields before trusting a city name that a geolocation service worked out from them.

Questions
How many data centres are in Connecticut?
The snapshot lists 16 facilities in Connecticut across 9 cities, among them Stamford, Norwalk, Hartford, New Haven and Waterbury. Between them they hold 16 network presences, so most buildings carry a single network and several carry none.
Is there an internet exchange in Connecticut?
No. The snapshot records no internet exchange in Connecticut and zero peers. Networks in Stamford, Norwalk and Hartford buy transit or carry traffic to exchanges outside the state, which means traffic between two Connecticut networks can be exchanged somewhere else entirely.
Can I get an IP address in Connecticut?
Placement follows the operator's address registration, not a customer's choice of state. A block reads as Connecticut when the network holding it registered a Connecticut address for that range. Mobile ranges are commonly registered once for a wider region, so a device's apparent state can differ.
